Fmoc-Arg(Pbf)-OH-13C6,15N4 is a protected arginine derivative bearing an Fmoc N-terminus and a Pbf (2,2,4,6,7-pentamethyl-dihydrobenzofuran-5-sulfonyl) side-chain protecting group, with isotopic enrichment at the arginine backbone carbon and nitrogen atoms (13C6,15N4). The molecule contains a free carboxylic acid functional group while the α-amino functionality is masked by the Fmoc carbamate, and the arginine guanidinium side chain is protected as the Pbf derivative to control chemoselectivity during peptide assembly. In synthesis and analytical workflows, the isotopic labeling enables mass spectrometric tracking and quantitative studies of incorporation or fragmentation patterns, while the orthogonally protected arginine scaffold supports stepwise construction of peptides via protected amino acid chemistry.
